SR 12 - Bouldin Island Project
The Bouldin Island Project will construct a new roadway section of State Route (SR-12) in San Joaquin County on Bouldin Island from the Sacramento County line from the Mokelumne River Bridge to Potato Slough Bridge. The project will construct two 12-foot lanes with standard 8-foot outside shoulders and 5-foot inside shoulders and a concrete median barrier. This project began construction in the spring of 2014.
The purpose of this project is to improve the structural section at various locations that have deteriorated due to the underlying oiled sand and to improve safety by widening shoulders and installing rumble strips. This project is needed because the existing shoulder width does not meet current standards and because the structural section contains oiled sand under the asphalt pavement, which led to settlement and cracking of the pavement at several locations within project limits.
State Highway Operation and Protection Program (SHOPP), 201.120 Roadway Rehabilitation 3R Program. Total Project Cost: $58,870,000.
End Construction: Late 2017
